Paint Dirt: remove operator call from Python

Instead of calling an operator I just call `collection.new()`. Moving the
code into a separate function also simplifies it. In its new form there is
also no undefined behaviour when me.vertex_colors is non-empty but without
active layer.

Cleanup: use workspace for object_mode when possible

Fix collection syncing when creating new collections from the outliner

We were not passing a scene collection parent to the BKE_collection_add
function, which in turn made syncing not work.

Right now we:
* Explicitly pass the master collection in this case
* Fallback to the master collection in other cases

With unittest.

Paint Dirt: some small fixes

- normalize ? average the vector: the vector isn't normalized here, because
it doesn't necessarily becomes unit length. Instead, the sum is converted
to an average vector.
- angle is the acos()?: the dot product between the vertex normal and the
average direction of the connected vertices is computed, and not the
opposite.
- The initial `con` list was discarded immediately and replaced by a new
list.
- File didn't end with a newline.

Cycles: unify OSL BSSRDF closure into a single bssrdf() closure with method.

This is similar to the upstream unified microfacet() closure, and makes it
easier to extend in the future.

Code refactor: tweaks in SSS code to prepare for coming changes.

This also fixes a subtle bug in the split kernel branched path SSS, the
volume stack update can't be shared between multiple hit points.

Code refactor: remove unnecessary RNG offset in branched path code.

This is only needed for SSS which bounces to a different shading point.

Cycles tests: separate directory for sss tests.

Disable fast adjust code. Add other end spec matching.

This fixes a few caess where new width adjustment code

was less than ideal.

Remove redundant check for armature mode

Caller ensures pose-mode, this flag is only set while drawing.
